a8c225cbaa support for embedded fonts in PDF documents. These
often do not have a 'cmap', 'post' and 'name' table and
were not loaded by FreeType previously..

(thanks to Derek B. Noonburgs from XPDF)

f126ee26e7 the TrueType glyph loader is now much more paranoid, this avoids
unpleasant overwrites in the case of invalid glyph data (found in
the output of buggy font converters)

the computation of auto-hinted stem widths has been modified to
avoid certain color fringes in LCD-decimation rendering (a.k.a.
"ClearType")

1c2ef2b948 * src/type1/t1objs.c (T1_Face_Init): fixed a bug that crashed the
library when dealing with certain weird fonts (like "Stalingrad",
        in "sadn.pfb". This font has no full font name entry.. )

        * src/base/ftoutln.c, include/freetype/ftoutln.h: added the
        FT_Outline_Check API to check the consistency of outline data

        * src/base/ftobjs.c (FT_Load_Glyph): added a call to the new
        FT_Outline_Check to ensure that loaded glyphs are valid. This
        allows certain fonts like "tt1095m_.ttf" to be loaded even though
        it appears they contain really funky glyphs..

        there still is a bug there though.. !!

ae69e7dc7d * src/cff/cffgload.c: added a comment regarding "cntrmask" operator
* src/pshinter/pshrec.c: now ignores invalid "hintmask" and "cntrmask"
        operators (instead of returning an error). Glyph 2028 of the CFF font
        "MSung-Light-Acro" couldn't be rendered otherwise (it seems its
        charstring is buggy, though this requires more analysis)..

constant with a fixed-float equivalent. For some reason, some compilers
        aren't capable of directly computing a floating pointer constant casted
        to FT_Fixed, and will link a math library instead !!
